JOSEPH WOLNY, or CARNEYViLLE, WYOMING.

COMBINED SLIDING AND SWIN GIN G CAR-DOOR.

To all whom it may concern:

Be it known that I, JOSEPH WoLNY, a subject of the Emperor ofAustria-Hungary, residing at Carneyville, in the county of Sheridan andState of Wyoming, have invented certain new and useful Improvements inCombined Sliding and Swinging Car-Doors, of which the following is aspecification.

This invention relates to certain new and useful improvements incombined sliding and swinging car doors. 1

An object of the invention is to provide a door for railway carsincluding two sections that may be moved into adjacent po-' sitionwhereby a closure for one-half of the door-way is provided and in whichthe door sections when so positioned may be moved to either the upperend or the lower end of the door opening. 7

A further object of the invention is to provide a door for railway carscomprising slidably associated door sections that may be slid in avertical directionto provide a complete or partial closure for thedoor-way, and that is capable of swinging movement to lie adjacent theroof of the'car so that the door-way of the car is wholly unobstructed.

With these general objects in view and others that will appear as thenature of the invention is better understood, the same consists in thenovel construction, combination and arrangement of parts hereinaftermore fully described, illustrated in the ac-,

view of a portion of a railway car with the door sections positioned atthe upper end of the door-way. Fig. 3 is a transverse sectional view ofa portion of a railway car 1 with both sections of the door at the lowerSpecification of Letters Patent.

end of the door-way. Fig. 4 is a similar view of the door sections slidupwardly and swung out of the door-way into posi- Fig. 5 is a horizontalsectional view of a portion of the railway car, more clearlyillustrating the mechanism for supporting the door when swung outwardlyfrom the door opening.

' Fig. 6 is a detached detail perspective view of one of the doorguides, and, Figs. 7 and 8 are detail perspective views, partiallybroken away, of portions of the upper and lower door sectionsrespectively.

Briefly described, the present invention aims to provide a door forrailway cars which includes two door sections that may be operated tocompletely or partially close the door-way in the car by a slidingmovement aflorded by guides at the sides of the door-way. The guides forthe sliding door sections positioned on the interior of the car may bemoved on pivotal connections to permit the door sections to swing on apivotal connection with the guides and be moved to a position adjacentthe car roof so as to be completely removed from the door-way.

Referring more in detail to the accompanying drawings, thereferencenumeral l0 designates a railway car of usual constructionincluding the floor 11, a roof 12, and roof supporting beams 13 whiledoor openings 14: are provided in the sides of the car.- The sides ofthe door openings 14 are provided with channel guides including verticalstiles 15 having vertical grooves 16 provided by inwardly-extendingflanges 17 and 18, the flange 17 being positioned at the outer side andbeing of greater depth than the inwardly-positioned flange 18 forpurposes to be later described.

A portion of each of the door sections is shown in Figs. 7 and 8, theupper door section being designated 19 and the lower door section 20,each of the door sections being preferably constructed of sheet metal.The lower door section 20 isprovided with a rolled lower end 21 whilethe side edges are turned inwardly as at 22 providing a pin extension 23at the lower end. As shown in Fig. 5, the upper door section 19 isslidably associated with the lower door section 20 and is guided in itsmovements by the inturned side edges 22 to prevent the disassembling ofthe sections. In assembled position, the pin extensions 23 are slidablyre ceived within the grooves 16 in the door stiles 15 which prevents thelower end of the door from swinging. A movable guide is associated withthe stile 15 and is positioned adjacent the upper end thereof and iscaused to engage the door sections 19 and 20 during their entire slidingmovements so that the upper end of the door may be prevented fromswinging inwardly. This guide is shown in detail in Fig. 6 and includesan angle-iron 24, the upper and lower ends of which carry pivotal pins25 adapted to be received in eye bolts 26 carried by the inner face ofthe stile 15. A latch 27 is provided to hold the guides 24 in operativeposition and is more clearly shown in Figs. 1 and 2, the latch 27 beinghinged to the inner face of the stile 15 and supported in its operativeposition by a keeper 28 carried by the said stile, it being noted thatthe projecting end of the latch 27 extends beyond the keeper to engagethe outer leg of the angleiron guide to prevent the same from swingingon its pivotal pins 25.

The mechanism for raising and lowering the door sections 19 and 20includes spaced depending brackets 29 carried by the car floor 11 andhaving journaled in the lower end thereof a rod 30 provided on one endthereof with an operating crank handle 31. Eye-bolts 32 and 33 arecarried respectively, by the upper and lower door sections 19 and 20 andare adapted to be selectively engaged by one end of the operating chain34, the said chain passing over guide rollers 35 positioned adjacent theupper end of the car 10 and continuing downwardly as at 36 from theguide rOllers to be connected to and wound upon the rod 30. Pawl andratchet mechanism 37 is provided on the rod 30 to prevent retrogrademovement when the chain is being wound in one direction. As shown inFig. 1, the chain 34 is connected to the eye-bolt 33 carried by thelower door section 20 and by operating the rod 30, both door sections 19and 20 will be elevated to the desired height by reason of the upperdoor section engaging the lower rolled end 21 of the lower door section.If it be desired to provide a complete closure for the door-way 14, thechain 34 is disconnected from the eye-bolt 33 and connected to theeye-bolt 32 of the upper door section and the rod 30 may then beoperated to cause the upperv door section alone to be elevated. It willbe noted that lifting chains for the doors are provided at each sidethereof and connect with the common operating rod 30.

The door and guides therefor are so constructed to permit the same to beswung completely from the door-way, it being noted that a release of thelatches 27 will permit the angle-iron guides 24 to be moved on theirpivotal pin connections 25 whereby the upper end of the door sections 19and 20 will be permitted to swing inwardly beyond the relatively shortflange 18. A support is provided for the door when the same is adaptedto be swung from the door opening 14 and includes, as more clearly shownin Figs. 3, 4, and 5, a U-shaped hanger 38 supported by the roof beams31 and hingedly connected thereto at its ends as indicated in Figs. 3and 4. A pair of guide rods 39 is connected adjacent their rear ends tothe hanger 38 while the forward ends thereof are connected by across-bar 4O projecting laterally of the guide rods 39 and provided withupturned ends 41. When the supporting rack is in inoperative position asshown in Fig. 3, the same is held in horizontal position adjacent thecar roof by a latch member 42 hinged to the upper frame of the door-wayand adapted to be swung to lie beneath and support the transverse bar40.

When it is desired to swing the door from the door-way 14, the liftingchains 34 are disconnected from the eye-bolts 32 and 33 and caused toengage the eye-bolts 43 carried by the lower door section 20 asindicated in Fig. 4. It being understood that the angle guides 26 weremoved to the position as shown in Fig. 4, the shaft 30 is operated tocause the chain 34 to be wound thereon and the door will be elevated andswung inwardly at its upper end to be slidably received on and supportedby the hanger and rack 38 and 39. The pawl and ratchet mechanism 37 willhold the door in any of its adjusted positions. In order to assist thepawl and ratchet in holding the door sections elevated, as shown in Fig.3, I have provided a pin 44 that mav be inserted within the opening 45in one of the side stiles 15 to support the lower end of the car doors.

From the above detailed description of the invention, it is believedthat the operation thereof will be readily apparent and while the formsof the invention herein shown and described are what are believed to bepreferable embodiments thereof, it is nevertheless to be understood thatvarious forms, modifications and arrangements of the parts may be madewithout departing from the spirit and scope of the invention as setforth in the appended claim What I claim as new is A device of the classdescribed, comprising a car having a side door opening, channel guidespositioned at the sides of the door pins carried by the lower rolled endof opening, a two-part door slidably and the lower door adapted forsliding engageswingingly mounted in said guides, the ment in saidchannel stiles, and means for 10 lower section of said door having arolled raising and lowering said door sections.
